Samba mountpoint hangs after server crash

2006-12-11 Thread Markus . Grunwald
Hello,

We have some trouble with samba together with a flaky windows NT 4.0 
Server: Quite often the server crashes and can't be reached again until it 
is rebooted. We mount some smb shares from that server and when the server 
crashes, we can't access the shares until root unmounts and remounts these 
shares.

This is a bit annoying, since root is not always available and has better 
things to do then remounting smb shares ;) I know, the best thing would be 
to fix the server, but nobody maintains this old machine...

Does the bug that is mentioned in the manpage Mounts  sometimes stop 
working. ... strike here ? I don't think so, because the mountpoint 
doesn't stop just like that, but because the server dies.

Some additional data:
Distribution: Debian testing
Kernel: 2.6.17-2-686

dpkg -l smb\*
ii  smbclient  3.0.23d-1  a 
LanManager-like simple client for Unix
ii  smbfs  3.0.23d-1  mount and umount 
commands for the smbfs (for kernels = than 2.2.x)

log.smbmount shortly after the server failed:
[2006/12/09 06:26:33, 1] libsmb/cliconnect.c:cli_connect(1369)
  Error connecting to xxx.xxx.xxx.xxx (Keine Route zum Zielrechner)

well, how heavily used are these mounts? maybe automount with a really
short time-out would work for you. automount would quickly umount the
shares when they aren't used thereby limiting the problem to those
times when the server crashes while someone is using the smb share.

or have root script something that checks for the presence of the
server and when its down, umounts all the shares, emails someone to
reboot the thing and then when it sees it back up, restarts the
mounts.
